My invention relates tovimprovements in.

the construction of chair structures.

An object is to provide a chairy element such as a back or a seat for a chair which seat, if the element is embodied inra seat, possesses the advantages of the slat type of chairseat and additional advantages of strength, durability and simplicity of construction which render it an improvement over the slat type of seat and which possesses advantages in utility and appearance over the slat type of seat and is here shown as embodied in a seat for a folding chair.

One object is the provision of a seat of this character wherein a ply wood seat section is employed in a seat frame and so constructed and mounted within the frame as to give the maximum amount of strength and durability and which, in addition to possessing certain advantages of the slat type of seat, also is so constructedV as to minimize any tendency of the upper veneer ply to' rupture or break while in use.

Other objects, advantages and meritorious features of my invention will more fully appear from the following specification, appended claims and accompanying drawing, wherein,-

Fig. 1 is a plan of a cliairrseat partly in section embodying my invention. Y

Fig. 2 is a cross-sectional view through the seat taken on the line 2-2 of Fig. 1 and showin a part of the supporting legl structure in dotted outline.

Fig. 3 is a section taken on the line 3-3 of Fio'. 1 showing a fragment of the sea-t.

Fig. 4i is a section taken on the line 1--41 of Fig. 1 showing another fragment of the seat.

In the drawing the impro-ved chair element is shown as embodied in a chairA seat. Chair seats have heretofore been formed with wood frames wherein slats were arranged to extend transversely of the seat frame being received within grooves formed in the inner edge of the side frame members and they have been formed of ply wood received as a unit within a groove formed in the side frame members and positioned below the Vupper sur- 59 face of the frame of the seat.

Iandl also ay similar .I provide a seat wherein a. ply woodrseat section is employed yof a novel kind which is fitted in a. novel manner within the usual-,seat frame so that the seat section, is flush with the upper surface `of the frame and the upper layer or veneer of ply Wood is scored transversely in imitation of seat slats, which scoiL ing acc'or'nplishes the useful purpose offseat n vslats iniendering the seat itself more adaptable for usefin serving toretain an occupant G0 1 t -tiierein and which furthermore minimizes any tendency'present in the upper ply wood layer to break or rupturewhile in use and to localize anysuch break` or ruptureV which might occur in one ofthe scores where it would not do any harm.

The seat frame comprises a pair of side frame members 10 connected in braced apart relationship and rear frame members 12 and llilrespectively. i are'pr'ovided along their inner edges with a groove 16 l hich registers with andis acon-y 4tinuation of a groove 20 -that.. extends along the inner edge of the front frame 'member 12 groove `22 that `extends "l5 along the innere'dge of the vrear fra-me member 14;; These frame members arev secured to? getherin la suitable manner such as by pins 24 shown in Fig. 1.`

A seat Asection is providedformed'of ply80 Vwood and I have hereshown'three layers indica-ted as 26, 28 and 30, respectively, `arrangedin the usual overlyingrelationship and glued together.V The two lowermost layers are vformed at theirmargins be received within the grooves 16, 20 and 22. The layer 28 is formed at its margin with a shoulder V311 which rises 4above the groove in' the frame member and abuts the inner edge 'of the frame member as shown in Figs. 3 and 90 e. The uppermost layer 30 is not received y within the groove but is fashioned to fit snugly within theframe member abutting the Y inner edges thereof whereby no strain is placed thereon by the groove in the frame and this upper layer4 is yscored at intervals providing a plurality of parallel spaced apart crosswis scores 36.V This scoring of theuper layercauses it topresent the appearanceV a sla't type ofseat and renders'it somewhat` 100 The sideframe members 10 70 *y as at 32 to 85 a frame comprising fashioned forI reception within a groove, one of said plies having a shoulder around its margin, and a transversely scored ply superposed upon the shouldered ply and lying within the confines of said shoulder.
